I would too.
A couple things I noticed were that his ch to LH hitters has more tail and his ch to RH hitters has more drop - obviously exactly what you want to see. Based on the highlights, he certainly looks like he throws harder than the gun reads and the velocity is consistent up or down in the zone.
The more I watch, the more I'm drinking the Kool-Aid, but I also try to be optimistic about these things.
